IMPROVEMENT lN CARPET-SWEEPERS.

Specification forming part of Letters Patent No. 125,369, dated April 2,1872.

To all whom it may concern:

Be it known that we, FREEMAN O. WILLEY and DANIEL B. McENnRY, both of LaFayette, in the county of Tippecanoe and State of Indiana, have inventeda new and Improved CarpetDuster 5 and we do hereby declare thefollowin'g to be a full, clear, and exact description of the same,reference being had to the accompanying drawing forming part of thisspecification, in which- Figure lis a perspective view, partly brokenaway to show the interior of the case; and Fig. 2 is a transversesection of the case taken in the plane of the line oo x, Fig. 1.

Similar letters of reference in the accompanying drawing indicate thesame parts.

Our invention has for its object toy provide for public use an improvedcarpet -sweeper and duster, which shall be simple and economical inconstruction, and more efficient in operation than those heretofore inuse. To this end the invention consists in the construction andcombination of various parts, as we will now proceed to describe. K

In the accompanying drawing, A is the rectangular or quadrangular caseofthe duster, formed with a cylindrical or curved front, and

.having its bottom partly closed by the strip B, so as to leave a narrowopening adjoining the lower edge of the curved front. C is the dust-pan,entering the back of the case and extending nearly or quite to the frontedge of the bottom strip B, and resting thereon. D is the handle of theduster, extending at an angle rearward from the top of the case, andprovided with a short stud or arm, E, carrying a wheel, F, which isadapted to run on the carpet in rear of the-case, and which also servesto support the machine in an upright position at the proper angle. G isa cylindrical brush, placed within the case immediately over the narrowopening in its bottom, with its ends or journals extending throughcurved slots h in the ends of the case. I is an adjustable frame orplate, extending longitudinally of the case upon the top thereof, andimmediately in front of the handle D, its ends being bent down toreceive the journals of the brush, and pivoted at j to the ends of thecase. lc is a thumb-screw extending through a lip, l, projecting fromthe rear edge of the frame I into the handle ofthe machine. By adjustingthe thumb-screw the frame is turned on its pivots to raise and lower thebrush, so that it shall bear with greater or less force upon the carpetduring the operation of sweeping. M is a roller, placed in front of thecase to prevent its coming in contact with and rubbing the carpet, andto smooth down the latter in advance of the brush. This roller has itsbearings in angular arms a, pivoted to the ends of the case, and is madeadjustable, to correspond with the adjustment of the brush, bythumb-screws o, which pass through the ends of the angular arms intoslots formed in the ends of the case. Motion is communicated to thebrush by means of a belt or cord, P, passing around a grooved pulley, R,afxed to the center of the brush-shaft, thence through a plate, S,attached to the top of the case, and around a large groovedcrank-pulley, T, upon the side of the handle near its outer end. Theplate S is made adjustable transversely ofthe case by slots andset-screws ato accommodate the movement of the belt when the brush isadjusted, and to dispense with the necessity of a slot, which wouldallow the dust to escape.

In using the duster the operator seizes the handle D in one hand toguide and push the machine along, while he operates the pulley T torotate the brush with the other hand. The drivin g-belt is crossed, asshown, to rotate the brush backward, so that the dust shall be takenfrom the carpet and carried entirely over the brush before it isdeposited in the pan. Owing to this arrangement the surplus dust notgathered is swept to the front of the machine to be taken up as thelatter proceeds, instead of being swept to the rear and left upon thecarpet. By constructing the front of the case cylindrical in form, theends of the bristles or brooms act against its inner surface to carry upthe dust and prevent it from dropping back to the carpet. Owing to therapid motion of the brush, a strong current of air is induced throughthe narrow opening in the bottom of the case, which takes up as muchdust as the bristles of the brush itself. The action of the 'bristleslifts the nap of the carpet, while the suction of the air picks up allthe fine dust and lint, leaving the carpet much brighter and newer inappearance than when swept by other means. The devices for adjusting thebrush v and smoothing-roller may be arranged inside as well as outsideof the case, if desired, without departing from the principle of ourinven tion. Y

Having thus described our invention, what We claim, is-

l. In combination Witli Jche case A and rotary brush R, We claim theadjustable supporting` frame I, substantially as described, for Iallepurposes specied.

2. The adjustable plate S, combined with the ease A and cross-belt P,substantially as described, fer the purposes specified.

3. The roller M, adapted for adjustment at the cylindrical front of thecase to correspond with the adjustment of the brush, substantially asdescribed, for the purposes specied.

4. The stud E, carrying the roller F, and affixed to the inclined handleD, in combination with the case A B, as described, for the purposesspecified.

5. The carpet-duster, consisting of the roundfronted case A B, the reardust-pa11,`the inclined handle, the adjustable smoothing-roller M, thebrush R, and the devices for operating and adjusting the latter,substantially as described, i'or the purposes specied.
